Help me please.
specs: intel s1200rp motherbard
intel e31246v3 3.5 ghz
128 gb ssd
8 gb ecc ram 1600 mhz
550 v smps
nvidia gtx 960 2 gb gddr5 graphis
Running on 1kva ups
Brought System in late 2015. worked nicely for long time error occurred once before but i ignored because later started working normally.
but from few months i was getting error beep 1-5-4-2 once in a couple of weeks, or month . which ruins my work.
What happened was a glitch on screen appears couple of times and then system turns off in next second.
I showed my system to my supplier he told me that nothing was wrong with it (actually error didn't occurred while he was testing)
but it happened again. can you tell me what the problem could be (system works fine apart from this error)
I'm sorry about hearing you have this intermittent issue since those are really difficult to troubleshoot. As you said BMC beep code 1-5-4-2 is related to the power feeding to the board but not necessarily an indication of failure of the power supply unit. Possible issue related to power could be:
- The power requirements exceed the nominal power output of the power supply (in your case 500 watt)
- The power requirements exceed the nominal power output of the UPS (less likely since its higher than the power supply capacity)
- On intel branded PSU the waveform emitted by the UPS should be pure sinewave otherwise it will cause issues under load
For troubleshooting purposes let me ask you how possible would be for you to try a different PS, connecting the power cord directly to the wall power outlet skipping the UPS and running high stress benchmark utilities so the whole server goes near to a 100% on processors, GPU, fans, SSDs, etc.
Keep me posted.
Apology for not being able to connect with you sooner,
I Appreciate your help.
I am happy to tell you that my problem has been resolved
Apparently there was a thick layer of dust was settled in my Power supply unit, which was somehow causing trouble
I did not realized before because i used to clean motherboard for clean dust but never actually opened psu. until recently which actually solved my issue.
May be you can add this solution to your troubleshoot option.
Thanks for everything
